We now know that for years visitors were given tours of the top-secret FBI tunnel under the Russian embassy. A ticket for the tunnel was also good for a ride on a submarine.
Even though there were tours and the tunnel has been discussed on "Good Morning Moscow," the tunnel is still classified top secret — lest they learn about it in the Senate Intelligence Committee.
When they dug the secret tunnel how did they get the dirt out of there? By truck in broad daylight. This brilliant ploy was devised by the spy, Robert Hanssen.
I can now tell you that we also dug a tunnel under the British embassy. What did they find down there? The Irish embassy.
